A good start, though the idea isn't particularly new. With work, could be a truly great game.
Suggestions:
Diversity, both in the area and in enemy types. I'd like to compete with other viruses, for one.
Upgrades....More of them! Also, have each upgrade affect a visual attribute of the cell.
I'd love to see a game similar to the cell stage of Spore...except with viruses!
It's a good game, but it's too hard to judge how big the cells are in comparison to yours. Maybe for a sequel you could highlight the cells that are small enough fo you to eat to make it easier. It just got to a point where the only hope would be to find one of the bonus's and hope its the one that allows you to eat any cell you want.
This game seems to be flawed. Several times I tried to eat a cell smaller than me and lost health, and at a certain point the game just stops sending cells small enough to attack
Really like this game. Didn't give it 5 stars because it was a bit laggy, but overall it was a great game.
the reason im giving it only half a star is because even if your 2 times bigger then the red cells you are suppose toe attack they still hurt you wtf???
